Herkenrath, Joel Whitburn
did not cherry-pick chart peaks from 1955-58 or before as you write - at least not with Elvis.
He has used exclusively the 'Best Sellers in Stores' chart which in itself I think is a reputable chart.
I have gone through the chart and all the 11 no. 1's are in the 'Best Sellers in Stores' chart. [This is including
Hound Dog / Don't Be Cruel as two No. 1's]
[You can
view it here, I have removed all lines [weeks] that did not include an Elvis song in at least one of the four charts.]
He did not just pick "the peak positions of a song in the various pop charts" as you say. I can't see how he would differ with other artists?
So he has used a consistent method and reputable chart up to the start of the Hot 100 in August 1958.
He would have decided not to use the Top 100 as it was only in use for less than three years and keep to the 'Best Sellers in Stores' chart to remain consistent for as long as possible, then switching to the Hot 100.
So he has used basically the 'Billboard chart of the day/era', he has used a consistent chart, and one based on sales, which to me is perfectly acceptable and with only a bit of a question over if Elvis' tally should come from the Top 100 or 'Best Sellers in Stores' chart, I consider either flows as evolution into the Hot 100, probably more so for the Top 100 however due to the fact that Billboard themselves have quoted up until at least 2008 charts complied from the 'Best Sellers in Stores' chart, I think it not only can be but must be counted in the modern rock era chart history.
Importantly it was in 2008 that Billboard announced that
Mariah Carey had surpassed Elvis Presley as the solo artist with the most No. 1 singles on Billboard's U.S Hot 100 Chart that it was revealed that they had ruled that Elvis' classic double sided number one hit single,
Hound Dog / Don't Be Cruel would no longer be counted as two separate number one hits. Billboard removed one number one hit from Elvis, and so Mariah was ahead.
So you see they were using this chart
and have now changed the 'rules' to suit their own needs that I believe to be for self-promotion, to be able to make public announcements and more suit those they sell their magazine too and those that advertise in it.
I quote a statement from Geoff Mayfield from Billboard magazine in 2008 regarding removing Elvis' double sided No. 1 hit.
'Billboard's charts department and the magazine's ranking trivia expert, Fred Bronson, consider those two songs comprise but one single, and thus a singular No. 1 shared by the two songs'. For now this is a separate subject. However you can see how big a hit it was and that
Don't Be Cruel did chart independently on the 'Best Sellers in Stores', 'Most Played by Jockeys' and 'Top 100' Charts and the combined two songs charted multiple times on all four charts, a monster hit. So Billboard had no right to once again re-write history and strip Elvis of two No. 1's for this single as they did in 2008.
So as Billboard had no problem including Elvis' number one hits up until 2008 [they would have needed to be able to quote new records and generate interest in their companies chart against opposition from 'CashBox' etc in the early year of the Hot 100 : just as they are doing today!!!] it is disingenuous to remove them now.
So I do think Billboard has dared to "rewrite the history books", and I am outraged about it.
I think looking at all their actions over the past three years they are a dishonest organisation and their motive corporate greed.
Bring back Cashbox anyone?
